My husband and I are going to Croatia and Slovenia this May.
Although
we are going on an organized group tour, we always do things
on our
own as much as possible, using the tour mostly for transportation,

lodging and some sights. On free times we do not take optional
trips,
but go off on our own. We are planning a trip for one day and
would
love any input as to whether this is too much for one day, are
all of
these places worth seeing, etc.

We want to rent a car in Opatija Croatia (I think Budget rent
a car
has a desk at the Millenium hotel where we are staying) then
drive
north into Slovenia to see Predjama Castle and then drive to
Lake
Cerknica. From there we want to take a short hike in Rakov
#kocjan to see the gorge and natural bridges. Next we want
to
drive south to the see picturesque (so they say) village of
Lo#
on our way to Sne#nik Castle (we love castles).

Then drive south through Risnjak National Park and then west
back
toward Opatija. If we have enough time we would also like to
drive
onto Krk Island and explore the Medieval Village of Vrbnik and
sample
some of their #lahtina wine before returning back to Opatija.

How does this sound? Do-able? Anything good we missed? What
about the
caves nearby?
